IMPROVEMENT IN THE ARRANGEMENT OF FEEDING 0R DELIVERY ROLLERS 0F CARDlNG-ENGINES.

Specification forming part of Letters Patent No. 3,094, dated May 19, 1843.

To a/ZZ wwm it may concern/ 'l Be it known that I, HORACE BAEBOUR, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Engines or Machinery for Oarding Cotton or other Fibrous Material; and I do declare that the following specification, taken in connection with the accompanying drawings of the said improvements, forms a full and exact description of the' same.

Figure l of the drawings above mentioned represents a side elevation, and Fig. 2 a vertical central and longitudinal section, of a carding-machine having my improvements appended thereto.

A, Figs. l and 2, represents the main drum or card-cylinder, and B is the runner or urchin or cylinder which receives the cotton from the tinted rollers. D and E are other card rollers or cylinders, these several cylinders being covered with card-teeth and. arranged, moved, and operatin g together in the usual manner.

It has been customary heretofore to use but two fluted rollers in order to convey the cot- Very long and necessarily small in their diameters, often spring apart from each other, and thus permit more of the fibrous material to pass bet-Weenl them than is desirable. My first improvement consists in arranging above these rollers, which are represented at a and b, Fig. 2, a third roller c, whose periphery is utd like that of each of the others, and which engages with the upper of them.

Fig. 3 is an enlarged view of the cylinder B and fluted rollers a b as the same are ordinarily constructed and arranged, while Fig. 4 exhibits them of dilerent diameters-that is, the diameter of a is much less than that of b, and they are combined together, andhave a third uted roller c, of larger diameter than that of the roller a, disposed above the upper of them.' The cotton passes between the rollers a and b and thence to the cylinder B, and by inspection of the ligure it will be observed that the distance of the point of junctionof the peripheries of the rollers a and b, Fig. et,

less than the distance of the point of junction of the rollers a. and Z9 in Fig. 3 from the periphery of the cylinder. Therefore, by supporting the smaller roller a by means of the third or supplementary flu ted roller c, l am enabled to successfully operate on cotton of a shorter staple than can be carded by the ordinary arrangement of the tluted rollers. p Besides, by the application of a rollerc above the roller a and increasing the diameter of the lower roller b lI can obviate the' dificulty above mentioned of the springing of the rollers apart from each other. The peripheries of the rollers ce and b should be placed as near to that of the cylinder B asis possible, to insure their correct operation together, -while that of the upper roller et, which should rest upon the roller c sufficiently to prevent it from springing upward, is arranged at a greater distance than the others from the cylinder B.

Fig. 5 represents the two iiuted rollers ce.

and b of equal but much smaller diameters than those ordinarily used, each roller being supported by a supplementary tinted roller, applied to it as seen in the drawing. By such a disposition of the rollers avery short staple can be carded by the machine. These iiuted rollers are moved and pressed down upon each other by means usually resorted to for effecting the same.

My next improvement consists in using a supplementary doier or cylinder G, which is placed directly under the main doier F, as seen in Fig. 2. This doffer G has a vibrating comb H arranged in front of it, and acting Y.

similar t-o that (via, l) of the upperdoffer. As

the card end of the fleece is removed from the 4 upper doifer by the comb mechanism l it passes through the tin-.plate or brass funnel' K, by which it is contracted, and from thence it is continued downward and joined to the fleece removed by the lower doifer, and which passes through the second funnel-plate L. By

one-half of the quantity presented and the other doffer the remainder, the following advantages are obtained: The main cylinder is .more effectually cleaned than by the ordinary arrangement of the mechanism, thereby preventing the staple from being repeatedly i carried around with the cylinder, which causes more or less breaking and knotting of the fibers as Well as the accumulation of more or -less Waste upon the cylinder., to the injury of Athe cotton. The combing operation is more The particularmethod herein described of arranging the delivering f'luted rollers or applying the same to the cylinder B-that is t-o say, forming one of the said delivering-rollers smaller in its diameter than the other and supporting the smaller by means of a supplementary roller c, also by constructing the said delivering-rollers of equal or unequal diameters and supporting both of them by a' tluted roller applied to each, by which peculiar arrangements I am enabled to successfully operate on cotton of a very short staple.

In testimony that the foregoing is a true description of my said invention and improvements I have hereto set my signature this L1th day of March, in the year 1843.
